I have an 870 coming and I was on the fence about the 18 inch barrel with just the bead or rifle sites. I have always really liked the idea of being able to line up a little more precise shot with rifle sites. I ordered the barrel with the tritium night sites, has anyone used these? I have shot a lot trap with bead sites so I feel comfortable with the bead, I have also shot quite a bit of iron site rifles in the past. Has anyone found a downside to Remington's rifle sites? Thanks.
